Fate/Ark

Prologue

Terra.

The planet where humans with animals and mythological traits from the history of Humanity.

A world infested with many dangers that seek to destroy all sentient life on this planet.

Originium. A powerful and dangerous source of power that all Terrans use for civilization. And Oripathy, a disease from Originium that cause the infected person to slowly become Originium itself and spread its infection to others.

The Infected were ostracized, discriminated of all nations in Terra due to this disease and fear it cause.

But, why do humanity continue to use this dangerous source of power?

Well, simply, its a better power source than the alternatives.

Solar panels cannot convert enough energy to power a mobile city, and due to the sky being fake...

Windmills are stationary and due to Catastrophe being dangerous and can happen in any time, the idea was thrown away.

Geothermal energy requires location where the planet's crust expose geothermal energy to be use, and its stationary, so, nope.

Nuclear energy... I don't think Terra have any nuclear ores like uranium, plutonium, or thorium to even produce nuclear energy.

So, with all alternatives check off, humanity continue to mine and refine this dangerous mineral for the sake of progression, with the sacrifice of those becoming Infected and discrimination.

For many nations, it's the necessary sacrifice worth, sacrifice the few to save the many.

But, one pharmaceutical company reject that idea.

Rhodes Island, a pharmaceutical company created to find a cure for Oripathy and distribute to the world. Their goal is to reject the notion mindset to give the Infected a chance to live their lives the way they want to.

An ideal dream, but reality is cruel. No matter have many resources they pool to find the cure, they can only delay the inevitable. But, with stubbornness and determination, they continue to seek the cure for the Infected.

And, because of their stubbornness and determination to make that idealistic dream come true, the collective unconscious will of mankind responded. The planet's counterforce go through many worlds to see who will save the humanity they were created to protect. As they search, they found the answer.

And with this answer, it summon the heroes from Human History.

Long before the current humans live in Terra, there was once a thriving civilization that once live on the planet, before their destruction from Originium. The race that is the foundation of all the current races of Terra: the Ancestors, or more commonly, human.

These seven heroes the will is summoning is the same race of the Ancestors, but, because of the Ancestors have been wiped out, and due to the nature of the Servants being the embodiment of their stories, the will have to do something.

If the people of the world would discover their identity, the will fear that their mission will delay their mission of curing Oripathy.

So, it change their Saint Graph to blend in with the people of its world.

As it finalize everything, the will summon them.

These seven heroes, or Servants, have been summon.

Saber, Knight of the Sword.

Archer, Knight of the Bow.

Lancer, Knight of the Lance.

Rider: Knight of the Mount.

Caster: Knight of Magecraft

Assassin: Knight of Assassination

Berserker: Knight of Madness.

They descend from the heavens. The fake sky that traps and protect humanity... For the first time in records of humanity's existence, the fake sky was pierce by seven lights that descended beyond its atmosphere.

The people did not know except the few.

The Feranmuts look at the direction where the lights descended with shock and awe.

The Leviathans from the deep ocean of the world all open their eyes for the first time in their slumber.

The Beast Lords watch, waiting to see these new visitors are friend or foe.

The demons of the north all look at the light that pierce the fake sky.

And...

A cup fall from the woman's hand and shatter, spilling its content. She look from the window towards a direction where the lights descended.

Kal'tsit: Impossible... Are there still more that lives...!

As the light vanishes, the heroes reveal themselves.

A blacksmith who continue to forge countless swords for the purpose to create an ideal sword that can cut throw karma, destiny, causality, fate, resentment, and bonds.

A goddess known for being the goddess of beauty, good harvest, fertility, lust, war and discord from the first civilization of Human History and the one who send the divine bull on the first hero of humanity and the weapon of the gods.

A warrior who is the avatar of the god of war. Wielding eight different weapons on the battlefield, she is the Dragon of Echigo that fought in Japan's warring times.

The rider that brings death. In actuality, it is different than the rider from the Book of  Revelation; no, it is the embodiment that is the Black Death, the Spanish Influenza- it is death itself that will continue to exist for life to begin anew.

A demigod that cured death. He was the doctor that brought the existence of clinical medicine. Son of Apollo and the God of Medicine, he is the first doctor that give birth to humanity's development of medicine that will later cure diseases that were deemed incurable before the modern era.

The god of love that shot an arrow at Shiva for Shiva to sleep with Parvati and conceive a child, though Shiva retaliated by incinerating him, leaving him a formless mass called the Incorporeal One (Ananga). Angered by the gods and Shiva himself, they took the form of a woman to spite at the wife of Shiva and possibly find someone that can love them who they are and not their divine nature.

 A nurse that brought the origin of nursing and hygiene. Known as the Angel of Crimea, she brought the importance of nursing injured patients and cleaning that stop the spread of bacterias or other foreign invaders to the human body. She reform the medical care that was stagnant and brought changes that saved many lives and continue to exist to the modern age.

As the Servants open their eyes to see the world they were summon, they see their new appearance.

And, well, some oppose their new appearance- or traits they were given while the rest didn't care or were intrigued by their appearance the will given to them.

Anyways, the Servants took their first step in this foreign world as they follow the first mission the will given to them...

Create a clinic.
